Convert Kilowatts to Megawatts

1 kilowatt is 0.001 MW. One kilowatt is exactly 0.001 megawatts.

One kilowatt is 0.001 megawatts. To convert kilowatts to megawatts, multiply by 0.001; to go the other way, divide by 0.001 or multiply by 1000. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A thousand watts.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.

How do you convert kilowatts to megawatts?

  1. 1.Take the measurement in kilowatts.
  2. 2.Multiply by 0.001 — that is how many megawatts fit in one kilowatt.
  3. 3.To go back the other way, divide by 0.001, or multiply by 1000.

Worked example: 25 kilowatts to megawatts

Formula
kW × 0.001 = MW
Arithmetic
25 × 0.001 = 0.025 MW
Answer
25 kW = 0.025 MW

The factor is exact, so this figure is exact too — only the display is rounded.

What is a kilowatt?

A thousand watts. Electric motors, kettles and EV chargers are rated here, and a kilowatt is close to 1.34 horsepower.

What is a megawatt?

A million watts. Generating plant and grid capacity are quoted in it: one megawatt runs roughly 750 homes in the US at average draw.

How many megawatts are in a kilowatt?

One kilowatt is 0.001 megawatts, exactly. Going the other way, one megawatt is 1000 kilowatts. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.

Questions people actually ask

How many megawatts are in a kilowatt?
0.001. A million watts. Generating plant and grid capacity are quoted in it: one megawatt runs roughly 750 homes in the US at average draw.
How do I convert megawatts back to kilowatts?
Divide by 0.001, or multiply by 1000 — they are the same operation.

Other power conversions

Megawatts to kilowatts — the same conversion the other way.
